Abstract

Taking into consideration the similarity to annual courses characteristic of the number of days with thunderstorms at Polish synoptic stations, an attempt has been made to determine potential seasons of thunderstorm days per year. The stations were also capable of being grouped such that Poland could be divided into five thunderstorm regions. Differences in the thunderstorm activity characteristics of particular stations and thunderstorm regions are connected with both the circulation of the atmosphere and such local conditions, as relief, land cover or the influence of the Baltic Sea on the coast.
